Which of the following is a primary mode found on a camera dial?

Shutter Priority mode is considered a primary mode found on a camera dial because it allows photographers to have direct control over the shutter speed while the camera automatically adjusts the aperture to achieve a proper exposure. This mode is particularly useful for capturing fast-moving subjects or creating motion blur effects, giving the photographer the creative flexibility to manipulate how motion is conveyed in their images.

In contrast, while options like Night Vision mode, Portrait mode, and Landscape mode are useful, they are often categorized as scene-specific or automatic modes that cater to particular shooting conditions rather than providing comprehensive manual control over the camera settings. Primary modes like Shutter Priority, Aperture Priority, and Manual mode typically enable advanced photography techniques, allowing for greater creative input in various scenarios.
